Anisometropia causes some people to have mild vision problems, or occasionally more serious symptoms like alternating vision or frequent squinting. However, since most people do not show any clear symptoms, the condition usually is found during a routine eye exam. [8] For early detection in preverbal children, photoscreening can be used.
A diagnosis of myopia is typically made by an eye care professional, usually an optometrist or ophthalmologist. This is by refracting the eye with the use of cycloplegics such as atropine with responses recorded when accommodation is relaxed. [12] Diagnosis of progressive myopia requires regular eye examination using the same method. [12]

Effects of astigmatism. As the eye shifts its gaze from looking through the optical center of the corrective lens, the lens-induced astigmatism value increases. In a spherical lens, especially one with a strong correction whose base curve is not in the best spherical form, such increases can significantly impact the clarity of vision in the ...
Radial keratotomy (RK) is a refractive surgical procedure to correct myopia (nearsightedness). It was developed in 1974 by Svyatoslav Fyodorov, a Russian ophthalmologist. It has been largely supplanted by newer, more accurate operations, such as photorefractive keratectomy, LASIK, Epi-LASIK and the phakic intraocular lens. [1]
The procedure has been described as safe and predictable in treating myopia and astigmatism. [11] Because SMILE treatment is relatively new compared with other laser correction treatments, result studies are limited, but postoperative five year (SMILE) outcomes indicate that the results have been stable after 5 years of follow-up.

The aging eye condition [1] A person with presbyopia cannot easily read the small print of an ingredients list (top), which appear clearer to someone without presbyopia (bottom). Specialty: Optometry, ophthalmology: Symptoms: Difficulty reading small print, having to hold reading material farther away, headaches, eyestrain [1] Usual onset
A phakic intraocular lens (PIOL) is an intraocular lens that is implanted surgically into the eye to correct refractive errors without removing the natural lens (also known as "phakos", hence the term). Intraocular lenses that are implanted into eyes after the eye's natural lens has been removed during cataract surgery are known as pseudophakic.
